Carl,
I agree that a roller inductor is probably unecessary in a ham amp. And
I agree that reliability is a question. But in a tuner, I don't know.
It sure makes it a lot easier to tune some difficult antennas with a good
roller inductor. Of course, perhaps if the antenna is that difficult to
tune, it probably won't work that well either. Or perhaps I am just
being too anal in that I want my SWR at 1:1??? :-)
Either way, I kinda like roller tuners. I've got an old Heath model.
73,
Jon
